Abstract

L'invention concerne des dispersions et des composites particulaires qui comprennent du graphite et des particules d'alliage comportant à la fois des phases actives (par exemple Si) et des phases inactives par rapport à l'activité électrochimique avec des métaux alcalins ou alcalino-terreux (par exemple du lithium). Les particules d'alliage sont très dispersées en tant que particules primaires avec des particules de graphite et/ou à l'intérieur de la matrice de particules de graphite, d'une nouvelle manière, et peuvent être préparées à l'aide de procédés simples de traitement de fusion mécanique à sec. Dans les composites préparés, les particules d'alliage sont essentiellement incorporées entre des couches de la matrice de graphite. Des performances améliorées peuvent être obtenues lorsque ces dispersions ou composites sont utilisés dans des anodes d'insertion de lithium destinées à des batteries au lithium rechargeables, notamment une grande capacité, une bonne performance de cycle et une capacité de débit.
